Niobium Sheet & Plate

No matter what your end use is, Admat’s flat sheets, plates, strips and foils are manufactured to high standards which include ensuring that the material meets your specific requirements, as well as common industrial standards such as ASTM B393 R04210 or the more stringent ASTM B393 R04200 Reactor Grade specification. 

Our sheets and plates are cold rolled and vacuum annealed with proprietary reduction rates to ensure ideal metallurgy.  Each sheet undergoes a stringent inspection for dimensions, surface finish, and flatness.

Our niobium titanium alloys and ultra high purity niobium sheets & plates (R04220 RRR Grade) are engineered for superconductor, supercollider, and high energy particle accelerator applications.

Our Niobium sheet and plate are used in a wide variety of industries including:

  • Industrial Synthetic Diamonds
  • Superconductor and Supercollider
  • Thin Film Coatings for Glass and Fiber Optics
  • Nuclear Reactor
  • Jewelry
  • Chemical Processes
  • Commercial Lighting (sodium vapor)
